VoIP with e2e

Benefits

EFFICIENT TRANSIT through routers.

Bandwidth Traffic NOT hosted by Operator.

G3T's patented e2e Technology enables
the direct communication set-up between
two IP devices over the internet, regardless
of whether or not those devices are located
behind routers. This means that the Service
Provider does NOT have to host any of the
IP bandwidth traffic whether it be voice,
video, images, music or any other content.

e2e Technology is essentially a lightweight IP
signalling protocol which is available as a
bolt-on Server Software, and used together
with e2e client software by the IP device.

This has successfully been applied to internet
telephony (VoIP) where non-hosted IP-to-IP
calls can be made and available for the direct
transmission of ANY media content; currently,
voice, video, text, snapshot as well as voicemail
and call forwarding. www.VePhone.net

[Note: the VePhone, available with a real UK telephone number, has full integration with worldwide Landline and mobile network for complete connectivity to traditional telephony]

VoIP with SBC's

Cost Drawbacks

Session Border Controller's required.

Operator Hosts Bandwidth Traffic IN

& BandwidthTraffic OUT.

A progressively more common situation
globally is for access to the internet to
be through the use of routers, whereby
multiple devices can simultaneously
access the internet. These routers
apply network address translation to
control the connectivity of multiple IP
devices through one IP connection to the
internet.

When the receiving IP device is located
behind a router, then communication
between the devices over the internet
will invariably involve the Service (SIP)
Provider hosting the bandwidth traffic
for the whole duration of that IP-to-IP
communication, through its own Session
Border Controllers (SBC's).

In the past, this traffic essentially was
simple low bandwidth voice traffic,
however, vast bandwidth dependent
content is becoming increasingly popular
in the form of video, music, image and
file transfer etc.

The current alternative methods that
the SIP Service Providers may attempt
to implement to avoid hosting the IP
bandwidth traffic, is using STuN, TuRN
or ICE protocols; however, all these have
documented drawbacks either in terms of
universal applicability or reliability.

VoIP (no SBC's)

Drawback

Not work for Recipient behind Router.

When the receiving IP device is on a single
IP address and NOT located behind a router,
then communication is direct between
the devices over the internet, without
the Service (e.g. SIP) Provider hosting
the bandwidth traffic.

This situation, though less likely, and arises when
the receiving party is connected to the
internet by a modem (and not behind
a router). For the calling party it is
not relevant whether they are behind
a router or not.

As the Service Provider does not know
the situation of the receiving party, it
cannot guarantee avoiding having to host
all the IP bandwidth traffic through its own
infrastructure in order to ensure that the
two parties communicate with each other.
